Ant venoms

Current Opinion in Allergy & Clinical Immunology, 2010
The review summarizes knowledge about ants that are known to sting humans and their venoms.Fire ants and Chinese needle ants are showing additional spread of range. Fire ants are now important in much of Asia. Venom allergens have been characterized and studied for fire ants and jack jumper ants.

Hypersensitivity to Fire Ant Venom

Annals of Allergy, Asthma & Immunology, 1996
Reading this article will reinforce the reader's knowledge of the taxonomy, origin, and distribution of fire ants and will increase his ability to diagnose and manage reactions caused by the two imported species, Solenopsis invicta and richteri. This review will also enhance the reader's knowledge of the available diagnostic methods and therapeutic ...

The chemistry of fire ant venom

Tetrahedron, 1971
Abstract Five alkaloids, three trans-2-methyl-6-alkylpiperidines, and two unsaturated analogues, have been identified in the venom of the red form of the fire ant, Solenopsis saevissima. The compounds are represented by the structural formulae I–V. Each has been prepared synthetically.

Alkaloids in the venom of Messor ants

Biochemical Systematics and Ecology, 2006
Tobacco alkaloids of the anabasine type have been found or confirmed in the venom of five species of arid-dwelling Messor ants. They are frequently accompanied by alkylpyrazines. Messor mediorubra contains four alkaloids, with anabasine the major component and also minor pyrazines.

Venom and Venom Apparatus of the Bull Ant, Myrmecia gulosa (Fabr.)

Science, 1964
The venom of Myrmecia gulosa (Myrmeciinae, Formicidae) is of a proteinaceous type and is separated by electrophoresis into eight components. The venom contains histamine, a hyaluronidase, and a direct hemolytic factor. It also shows kinin-like activity.

Ant Venoms: A Study of Venom Diversity

1978
Ant venoms appear to represent an almost untapped reservoir of information capable of adding several exciting chapters to the story of toxinology. Ants share with some bees and wasps the distinction of being the only truly social group of venomous animals. This fact implies that most of the venomous individuals belong to an essentially sterile class of

Anabaseine: Venom Alkaloid of Aphaenogaster Ants

Science, 1981
Anabaseine, a tobacco alkaloid, is identified as a poison gland product in Aphaenogaster ants, in which it functions as an attractant.

Novel Dialkylpiperidines in the Venom of the Ant Monomorium delagoense

Journal of Natural Products, 1990
New 2,6-dialkylpiperidines found in the venom of the ant Monomorium delagoense include cis- and trans-2,6-di(4-pentenyl)-piperidine [2], cis- and trans-2-(4-pentenyl)-6-pentylpiperidine [4], and cis- and trans-2-(6-heptenyl)-6-(4-pentenyl)-piperidine [7], whose structures were confirmed by synthesis.

Teasing apart ant venom

Science, 2018
Organismal Biology![Figure][1] The giant red bull ant has complex multifunctional venom. PHOTO: KAAREL OLESK/GETTY IMAGES Ant venoms are primarily made up of poorly characterized polypeptides. Robinson et al. combined transcriptomics and mass spectrometry–based proteomics to determine the mechanism of action of giant red bull ant venoms.
